Hi,

I noticed that there has happened some deprecation with GeoPackages since 
released OpenJUMP 1.12. Version 1.12 detects and utilizes the spatial index of 
a table which makes it very fast to use even huge tables if map is zoomed close 
enough.  New snapshots do not utilize spatial index which makes OJ very slow 
with large tables. I have not yet analyzed more closely when this change has 
happened. It seems that the layer list is sorted differently now than in 1.12. 
Perhaps that change is related.

I believe that the detection is done here
